Because his advanced stats say so. Duh! You get such a hard on for players based on small sample sizes of advanced metrics. And you always ignore situational usage, which is even more impactful on bad teams.
Meanwhile a few posts up you commended Zacha for taking shots he didn't take last year....when in reality:
Last year 1.623 S/PG
This year 1.627 S/PG
Also note he's averaging over 80 seconds more TOI this year.
And no, I'm not gonna buy that you meant his shot selection is better or more confident. He was streaky just like this last year. Hell, he's done it earlier this year as well. A few games of looking great and then disappears for a dozen.
